Radial nerve palsy

A 17-year-old man with no familial history developed motor and sensory disturbance of the left upper limb a few days after starting push-up exercise. Neurological examination revealed broad weakness and radial sensory disturbance of the left upper limb and magnetic resonance neurography showed laterality of brachial plexus intensity signals. Therefore, we suspected left brachial plexopathy. However, a nerve conduction study showed a broad disturbance that could not be explained by only brachial plexopathy. Genetic tests revealed a diagnosis of hereditary neuropathy with liability to pressure palsies (HNPP)...

Treatment of brachial plexus injuries has slowly improved over the last 45 years. Changes in strategy, techniques, microsurgical equipment and technology have expanded the surgical options to reconstruct these life altering, highly complex injuries. The surgical armamentarium includes neurolysis, nerve repair, nerve grafting, nerve transfers, tendon transfer, muscle transfer and other soft tissue and bony procedures. In this article we have selected five surgical procedures (Oberlin's procedure, Leechavengvongs' procedure, free functional muscle transfer, radial nerve tendon transfers and C5-C6 nerve grafting in obstetrical birth palsy) that have consistently given us good results in our patients who require surgical reconstruction...

PURPOSE: To evaluate the time to bone union after open reduction and internal fixation with cerclage cables followed by intramedullary nailing (IMN) for unstable humeral shaft fractures. MATERIALS AND METHODS: Patients with a humeral shaft fracture treated by IMN were enrolled. One group of patients was treated via open reduction and internal fixation with cables followed by IMN (cable group; n=32), while the other group was treated with a conventional closed IMN (non-cable group; n=64)...

A giant intracranial internal carotid artery(ICA)aneurysm is difficult to treat. We encountered a case with an unruptured giant intracranial ICA aneurysm with a ruptured C2 aneurysm of the ipsilateral ICA. In this case report, we describe how the treatment and review the literature. A 59-year-old man presented with sudden-onset headache and vomiting. He was diagnosed at a local neurosurgical unit as having a subarachnoid hemorrhage and admitted to our hospital. Cerebral angiogram revealed an unruptured giant ICA C3-4 aneurysm with a ruptured aneurysm of the ipsilateral ICA C2...

BACKGROUND AND IMPORTANCE: Hourglass-like constrictions are fascicular conditions confirmed definitively by interfascicular neurolysis. Certain peripheral nerves have vulnerable areas such as around the elbow in the posterior interosseous nerve. We report the first hourglass-like constriction in the brachial plexus supplying the radial innervated forearm musculature. Preoperative magnetic resonance imaging (MRI) findings of the brachial plexus were consistent with neuralgic amyotrophy (NA)...

INTRODUCTION: Radial nerve palsy is a rare but serious complication following elbow external fixation. Only 11 cases have been reported in the literature to date, but the incidence may be underreported. We present three new cases of this complication. MATERIALS AND METHODS: We analyzed the three cases of radial palsy seen in our center following the application of an external fixator as treatment for complex elbow injuries. RESULTS: Mean patient age at surgery was 50 years...

As a result of its proximity to the humeral shaft, as well as its long and tortuous course, the radial nerve is the most frequently injured major nerve in the upper limb, with its close proximity to the bone making it vulnerable when fractures occur.Injury is most frequently sustained during humeral fracture and gunshot injuries, but iatrogenic injuries are not unusual following surgical treatment of various other pathologies.Treatment is usually non-operative, but surgery is sometimes necessary, using a variety of often imaginative procedures...

OBJECTIVES: to determine if time from injury to fixation of diaphyseal humeral fractures and nonunions is associated with the risk of iatrogenic radial nerve palsy. DESIGN: Retrospective review. SETTING: Two level 1 trauma centers. PATIENTS/PARTICIPANTS: Between 2001 and 2015, 325 patients were treated with fixation of a humerus fracture or humerus nonunion who had documented intact radial nerve function pre-operatively...

Posterior interosseous nerve palsy caused by a ganglion is not common and most previous patients were treated with excisional surgery. We treated a case conservatively with needle aspiration using ultrasonography, after a nerve conduction study. A 77-year-old man presented with impaired active finger extension of the left metacarpophalangeal joints. The nerve conduction study revealed conduction block of the left radial nerve near the elbow. Ultrasonography demonstrated a hypoechoic mass anterior to the radial neck compressing the posterior interosseous nerve...

Brachial plexus birth palsy resolves spontaneously in a majority of patients, however, others may have serious permanent dysfunction. Although nerve transfers or grafts are early options for treatment, many children have residual deficits or present too late for such procedures. In these patients, rotational osteotomy of the humerus may restore improved function and motion. Unfortunately, traditional humeral osteotomies only provide correction in a single plane, therefore appropriate correction of the typical residual deformity is incomplete...

BACKGROUND: Amyloidosis affecting peripheral nerve is usually seen in primary amyloidosis. METHODS: We are reporting on the case of a 74-year-old man with a 16-month history of progressive left radial nerve paralysis. Perioperative imaging detected an enlarged radial nerve in the middle-distal part of the arm. The patient had an antecedent of amyloid deposits in the lung. RESULTS: A radial nerve amyloidosis was suspected and confirmed with a biopsy assisted by ultrasonography, resulting in a secondary amyloidosis form...

When using elastic stable intramedullary nailing in children's distal radius shaft fractures, the surgical approach can either be lateral or dorsal. The aim of this article was to carry out a systematic review of the literature comparing the two types of approaches in terms of complications. An electronic search of databases was performed. Titles of articles were screened, and abstracts and full text were read. Data were extracted in terms of demographics and complications. The dorsal approach had a 2.6% rate of extensor pollicis longus tendon rupture, whereas the lateral approach had a 2...

BACKGROUND: Triceps reinnervation is an important objective to pursue when repairing the brachial plexus for cases with upper roots injuries, and a number of different techniques have been developed in order to restore elbow extension in such cases. OBJECTIVE: To demonstrate the surgical outcomes associated with the technique of transferring a single healthy motor fascicle from the radial nerve of the affected arm to a branch innervating 1 of the 3 heads of the triceps...

RATIONALE: Elbow injury in children by improper treatment or a delay of more than 3 weeks could lead to old unreduced Monteggia fracture, which are difficult to manage. Conservative or normal surgical methods usually fail. PATIENT CONCERNS: Herein, we present a 6-year-old boy with sustaining injury approximately 1 month to his left elbow. Activity in his elbow was restricted, and his ability to extend his wrist and fingers was impaired. DIAGNOSES: Type III Monteggia elbow fracture-dislocation consisting of radial head dislocation and malunion of the ulna associated with posterior interosseous nerve palsy were confirmed, which requiring surgical treatment...

INTRODUCTION: The incidence of radial nerve injury after humeral shaft fractures is on average 11.8% (Shao et al., J Bone Jt Surg Br 87(12):1647-1652, 2005) representing the most common peripheral nerve injury associated with long bone fractures (Korompilias et al., Injury, 2013). The purpose of this study was to analyze our current policy and long-term outcome, regarding surgically treated humeral shaft fractures in combination with radial nerve palsy. MATERIALS AND METHODS: We retrospectively analyzed the data of patients with surgically treated humeral shaft fractures from 01/01/2003 to 28/02/2013...

BACKGROUND: Endoprostheses using principles of compressive osseointegration have shown good survivorship in several studies involving the lower extremity; however, no series to our knowledge have documented the use of this technology in the management of massive bone loss in the upper limb. QUESTIONS/PURPOSES: (1) What proportion of upper extremity implants using compressive osseointegration fixation principles achieved durable short-term fixation, and what were the modes of failure? (2) What surgical complications resulted from reconstruction using this technique? METHODS: A multiinstitutional retrospective review identified nine patients (five women; four men) who underwent 13 endoprosthetic replacements between 2003 and 2014 using compressive osseointegration (Compliant(®) Pre-stress Device [CPS]; Biomet Inc, Warsaw, IN, USA) in the upper extremity, including two proximal humeri, two humeral diaphyses, seven distal humeri, and two proximal ulna...

OBJECTIVES: To introduce a stepwise percutaneous leverage technique to avoid posterior interosseous nerve (PIN) injury in pediatric patients with radial neck fractures and to evaluate the clinical outcome and the predisposing factors affecting the outcome. DESIGN: Retrospective case series study. SETTING: University level 1 trauma center. PATIENTS: Thirty-four children with a radial neck fracture, who were treated using a stepwise percutaneous leverage technique, were included in the study...

BACKGROUND: Symptomatic bilateral extracranial internal carotid artery (ICA) aneurysms at the subpetrosal portion are extremely rare, and their treatment strategy remains unknown. CLINICAL PRESENTATION: A 42-year-old man presented to our hospital with a 2-month history of sudden onset of hoarseness, dysarthria, and dysphagia. Magnetic resonance imaging, magnetic resonance angiography, and computed tomography angiography revealed extracranial bilateral ICA aneurysms at the subpetrosal portion...

BACKGROUND: Nonunion is a rare but severe complication following forearm fracture in skeletally immature patients. The purpose of this study is to describe a case series of pediatric forearm nonunions treated at our Institute. MATERIALS AND METHOD: We retrospectively reviewed medical charts and radiographs of healthy children affected by post-traumatic nonunion of the forearm, from April 1992 to July 2015. An overall series of 15 cases was included in the study...

The aim of this study is to evaluate the complications of humeral lengthening and their associated factors. Fifty-four achondroplastic patients were treated by bilateral humeral lengthening. Our original shoulder sling was sufficient to prevent shoulder dislocation. Pre-existing radial head dislocation was observed in 18 patients. Lengthening was accomplished in all cases without a decrease in the elbow function. Seven humeri fractured after the fixator removal. The risk factors for postoperative fracture were a waiting period of less than 5 days, a healing index less than 25, and the concave shape of the callus...
